garpinc created OPENJPA-2263:
--------------------------------
Summary: Update statements should not update the primary key of
database unless the primary key has in fact changed
Key: OPENJPA-2263
URL: https://issues.apache.org/jira/browse/OPENJPA-2263
Project: OpenJPA
Issue Type: Bug
Components: jdbc
Affects Versions: 2.2.0
Reporter: garpinc
I have encountered a situation while creating an openjpa dictionary for
teradata. It seems teradata does not like it when the primary key is updated.
i.e: update tablex set pk=1 where pk=1;
Following the code it seems RowImpl.java contains a method getUpdateSQL which
uses the dictionary to various things but it doesn't allow the dictionary to
change the statement itself.
The specific functionality I need here is to only update the pk if the pk has
changed or maybe an option not to update the pk at all.
